Gemma 4 E2B Thinking Toggle Stumps Ollama Users

The real issue here is an API mismatch, not a lack of documentation: Ollama supports disabling thinking, but only when the client can actually send the flag or control the system prompt. For beginners building local workflows, this is the kind of friction that makes “local AI” feel simpler on paper than in practice.

• –Ollama’s docs say `think=false` is the supported switch, which means the clean fix is request-level control rather than editing the model itself.
• –If the client cannot pass API parameters, a wrapper service or proxy layer is the practical workaround, not a Modelfile tweak.
• –The question highlights a growing pain point for local LLM users: model defaults, runtime behavior, and app integrations do not always line up.
• –Gemma 4’s reasoning-oriented positioning is useful for agents, but overkill for dictation cleanup, where latency matters more than deliberation.
